NCBI Submssion

generate_ncbi_gss.py: A script to create .gss and the parallel .pub, .lib, and .cont files from .fasta files containing environmental fosmid-end sequences for submission to dbGSS. For more information see the official dbGSS website at the NCBI.

Analysis

calculate_4mer_freq.py: A script to calculate the tetra-nucleotide (4-mer) frequency from a set of .fasta files, creating a matrix of all 256 4-mers as a tab-delimited file --- ready for loading into R.
